The resignations within her own Tory party are now following each other in quick succession for PM Theresa May as this morning Mr Scott Mann, the conservative Member of Parliament for North Cornwall decided to step down as parliamentary private secretary to the Treasury as he claimed he could, just as Foreign Minister Boris Johnson stated last week, not support a “watered-down Brexit”.

The news means Prime Minister Theresa May is in an ever more isolated position as she tries to defend her plan which was an agreement achieved at the PM’s retreat at Chequers last weekend, a deal that saw two of her top ministers resign and US President Trump exclaim that her sort of ‘Brexit’ plan was ‘not what the people voted for’.

Furthermore, she now faces further betrayal as there are also those within her own Tory party openly calling for a second referendum.

Writing in the Times, the former Education Secretary Ms Justine Greening claimed that the “only solution is to take the final Brexit decision out of the hands of deadlocked politicians” and let voters have a final choosing between three possible options: PM May’s Brexit plan as agreed at Chequers, a no-deal or so-called ‘Hard’ Brexit or, lastly, staying in the EU.

Asked whether she believed other Tory politicians backed her idea for a ‘second Brexit referendum’, she explained: “Yes, because I think in practice it suits no one, and whether you’re a remainer who looks at it and thinks, actually, we’re signing up to all the rules but now we won’t be around the table to influence them, or indeed you’re a leaver, who says this doesn’t give us the clean break we want, it doesn’t keep anyone happy.”

“I think that millions of people who voted for leave will feel that this approach is not what they voted for in the referendum in 2016. The basic problem we’ve got is that Westminster works on party lines, but Brexit is above party politics, and so in a way it’s not set up to deal with this issue.”

The news comes as Ms May is faced with an ever tighter deadline to present her Brexit negotiation strategy. The deadline to come up with a Brexit deal for the UK’s new relationship with the EU runs out in March 2019 and much remains on the negotiating table.

Ms Greening: “We have to be pragmatic now about the fact parliament will not be able to take a decision on this final deal. I don’t believe what we need is more time. What we need is a proper decision that we can follow through on as a country.”
